There are multiple mathematical series that can be used to calculate pi without using a circle. Gregory-Leibniz series and Nilakantha series are two examples.

Ok write down pi in decimal form, that's how hard it is to draw a perfect circle.

I would say that a perfect circle is a regular geometric polygon in which the diameter/circumference ratio is exactly pi.

A compass circle is not a perfect circle because it's not perfectly regular, just nearly, and as such its ratios will be very close to pi.

By your absurd definition, you couldn't ever have a perfect circle because quantum mechanics.

I've clarified my definition. Is it still absurd?

Yes.

Circles are not polygons. Absurdity still in effect.
